WiRE-NETTING MACHINE.

Application filed March 11, 1886.

To all whom it may concern.-

Be it known that I, EDWIN GILBERT,. of Georgetown, in the county of Fairfield and State of Connecticut, have invented a certain new and useful Improvement in Wire-Netting Machines, of which the following is a specification.

My invention relates to the class of machines represented in Letters Patent No. 310,251, granted January 6, 1885, to Hiram Combs. Machines of this class are employed in male ing wire-netting having hexagonal or other polygonal meshes, which are formed. by twisting each wire alternately wit-h the wires on the opposite sides thereof and deflecting it between the points of twisting. In such machines are employed a line or row of upper and lower spindles havingsectional upper and, lower journals and pinions which are divided axially, half of each journal and pinion being formed integral with the spindle, and the other half being made separate from the spindle, but operating in connection therewith to pro duce the netting. The journals are fitted to bearings which are formed in the meeting edges of slides, each slide containing semicircular recesses or notches, which form half circular beuri ngs, and,as described in the aforesaid Letters Patent, these slides, or one of them, has a reciprocating motion which is suificient to bring the halfjournal and pinion portions pertaining to each spindle into coincidence with the halfjcurnal and pinion of the spindle adjacent thereto. A wire is conducted through each portion or half of the upper journals, and by the shifting of the slides in which the bearings of the journals are formed and the rotation of the journals by racks engaging with the pinions the wires will be properly intertwisted, as is described in the aforesaid patent.

In the machines of this class as heretofore constructed one wire of each pair is taken through the half portions of the journals and bearings which are separate from the spindles, and the other wire of each pair is taken from a spool or bobbin, or from a cop-case which is held between the oppositely-arranged spindles of a pair. When the second wire has been taken from a spool or bobbin, it has been necessary to provide a radial opening or hole in the upper spindle, in order to conduct the "i-PESEPICATIQN forming part of Letters Patent No. 341,230, dated May 4-,1886.

wire to the hole or perforation which is pro vided therein for the wire. \Vhen the wire is taken from a cop contained within a copcase, the spindle through which the wire is conducted is offset and provided with an out side guide for the wire. The spindle being thus oifset has not been properly balanced, and hence when the wire has been taken from a cop in a cop-ease it has not been possible to drive the spindles as fast as is desirable for economical working.

The object of niyinvention is to enable copcases to be used with spindles which are properly balanced and can be rotated at a high speed.

To this end the invention consists in the combination, with upper and lower spindles constructed with sectional journals and pinions, one spindle of each pair having a direct passage through it from end to end, of copcases between the pairs of spindles for containing cops, from which thewire is conducted through the said direct passages in the spindles.

In the combination above described one spindle of each pair is preferably constructed with a socket containing a spring, the other spindle of thepair having asocket or pivot seat, and the cop-casc h as pivots or projections for engaging said sockets. The copcase may then be placed in position by inserting the pivot or projection into the socket in which is the spring, and the spring will yield to enable the eop-case to be moved laterally to bring it in line with the spindles, and by its resilience will. hold both pivots thereofin engagement with the spindles.

The above features 01' construction are included in my invention.

In the accompanying drawings I have only represented such parts of a machine of the kind above described as are necessary to illustrate my invention.

Figure 1 is a transverse section of the upper and lower slides and racks and upper and lower spindles,with an interposed cop-ease an ranged between them and journaled in said slides, and adapted to be rotated bysaid racks; also including portions of the f'aniing of the machines and rollers by which the completed netting is taken up; and Fig. 2 is a vertical section,upon a larger scale, of the upper and kJI lower slides and racks and the two spindles, with an interposed cop-case and cop, a portion of the cop and case being broken away to reduce the vertical dimension of the drawings.

Similar letters of reference designate corresponding parts in both figures.

A designates portions of the frame-work of the. machine, which may be of any suitable construction, and 13 B designate the rollers by which the completed netting is taken up after being made.

O C designate upper and lower spindles, a number of which will be arranged in line widthwise of the machine, and D designates a cop case, which may be of sheet metal or other material, and which is arranged between and engaged with the two spindles and contains a coil or cop of wire, D. The upper and lower spindles, C 0, each comprise an integral half portion of ajournal, c, and ahalf portion of a pinion, 0. Made separate from but operating with such halfjonrnal and pinion portions are other hal f-jou rnal and halfpinion portions, 0* (1*, which complete the cylindric journals and pinions of the upper and lower spindle.

E E designate upper and lower pairs of slides, which have formed in their meeting edges bearings which receive the upper and lower journals, 0 0*, and between the slides of each pair are racksF F, which engage with the pinions c c*, and impart rotary motion to them and to the spindles G O.

The slides and racks E F E F may be reciprocated by mechanism such as is described in the aforesaid Letters Patent to Combs, or by any other suitablemechanism. One wire, 8, of each pair passes upward through pcrforations in the journal portions 0*,which are separate from the spindles, and the other wire, 8, is taken from the cop D within the co p-case, and is carried directly through a perforation or hole, (Z, which extends directly through the upper spindle, C, from end to end thereof, and above said upper spindle the wire 8 is combined orintertwisted with the wires, as will be readily understood from the aforesaid patent.

By the employment of the cop'caseD,which is engaged with upper and lower spindles, as described, and byt'ne construction of the spindle G with a hole or perforation, (1, extending centrally and directly through it from end to end thereof, I am enabled to feed the wire 5 directly through the spindle O, and to employ a spindle which is perfectlybalaneed, without the necessity of passing the wire 3 radially into the said upper spindle to meet the hole or perforation (1, extending through the same,as is done in the Letters Patent above referred to.

In order to provide for the ready engagement and disengagement of the cop-case D- with and from the spindles, I form in one spindle (in this instance the lower one, 0) a socket, c, of considerable length, and which contains a spring, 6, and I form in the upper spindle a conical socket, 0 The cop-case D is provided at opposite ends with pivots or projectionsf f, and it will bereadily understood that by first introducing the pivot or projection f into the socket c and pressing it downward so as to compress the spring 0, the upper pivot, f, may be moved laterally opposite the upper spindle, O, and by the resilience of the spring 0 the cop-case will be raised, so as to press the pivotf into the seat or socket c.

That I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with upper and lower spindles arranged in pairs and constructed with sectional journals and piuions, as described, one spindle o'teach pair having a direct passage through it from end to end, of cop-cases between the pairs of spindles for containing cops, from which the wire is conducted through the said direct passages in the spindles, substantially as herein described.

2. The combination, with upper and lower spindles arranged in pairs and constructed with sectional journals and piuions, as described, one spindle of each pair having a socket containing a spring and the other having asocket, of cop-cases having at the ends pivots or projections, before one of which the spring will yield, to enable the other pivot or projection to be entered into the socket in the opposite spindle, substantially as herein described.
